A study on the carbon soot derived from the wood combustion and on the relative alkali-extractable fraction

Abstract

In this experimental study, waste particulate of domestic flame combustion of wooden matters have been reacted according to a direct mild-condition reductive-oxidative chemical synthesis. Water-soluble graphenic and polycyclic aromatic frameworks have been extracted from graphitized carbon residues. Products have been recovered by elemental carbon contented in both fly and bottom combustion particulate. Their pH-sensitive behavior in aqueous solutions has been elucidated. Products and reactant substrates have been spectroscopically characterized by mean of solid state vibrational FT-IR and Raman, UV-VIS, XRD, solution 1H and 13C NMR, SEM-EDX and MALDI-TOF MS techniques. Discussion upon the reactivity of flame carbon residues of wooden matters is reported, in comparison to the reactivity displayed by other graphenic structures, according to the reported synthetic protocol.
